A capacitor with an initial potential difference of 100 V is discharged through a resistor when a switch between them is closed at t=0. Att - 10.0 s, the potential difference across the capacitor is 1.00 V. (a) What is the time constant of the circuit? (b) What is the potential difference across the capacitor at t= 17.0 s?
